Hello everyone,

 

I am wondering if everyone can share how they determine what microorganism or pathogen a product is susceptible to. I do this by researching all ingredients used in the product when we develop new products. I want to be sure I am doing it right or if there is a better/advance/technical way to do this. Everyone's share of knowledge will be highly appreciated.

 

Thanks in anticipation!

There are certain pathogens associated with different food groups and others which are more ubiquitous. For example, any chilled factory processing ready to eat or reheat, the factory itself becomes a potential Listeria monocytogenes risk. What is it you're processing?

ICMSF is a good resource for this 

 

Here is the second edition from my own library:  ICMSF 2.pdf   812.8KB   4 downloads

 

But, yeah just research industry, regulatory, and academia for determining microbiological hazards for the finished product.

Hi Omoware,

 

Hazard Analysis and Risk-Based Preventive Controls for Human Food: Draft Guidance for Industry is a useful reference.

In particular: Appendix 1: Known or Reasonably Foreseeable Hazards (“Potential Hazards”) and A1.10 Tables of Known or Reasonably Foreseeable (“Potential”) Food-Related Biological Hazards.

 

For less common products I would normally be steered by the food category they fell into.

 

Kind regards,

 

Tony

The "bad bug book" is another good resource.

No matter how uncommon a food product is to you, there will be a companies who are specialized in that type of product. I have found that each type of product has an organization that represents multiple businesses in that field together and they often publish standards that include biological hazards in their field. I've literally read up on products I was unfamiliar with using the information from such organizations.

Thanks!

We process RTE sauces and condiment (mostly cold mix, no cooking)

When you don't include a kill-step in your processing, your final product is a high risk susceptible to most pathogens, including environmental contamination that didn't necessarily come from an ingredient. The only way to get this right is to make sure your product is acidic enough and that it is impossible for pathogens to grow to dangerous levels during its shelf life. Keep in mind that particulate matter can cause micro-environments with local differences in pH and such.

 

And all this needs to be validated.

Thanks a lot for this. It is a very helpful information.
